W/Mo Crucible are used in growing sapphire, crystal and rare earths industry. W/Mo Boat are mainly used for sintering and annealing of both Metal and Nonmetal Materials in Reduction Atmosphere, and also as Sintering Boat for powder products, such as sintering precision ceramics. (Tungsten Crucible) (Molybdenum Boat)
the bottom. Because the sapphire boule sticks to the crucible at the end of the growing process, boules can crack at the cool down process and the crucible can only be used once. Any of these sapphire crystal growing technologies have in common that core components - particularly crucibles - are requiring high-temperature refractory metals.
The Mo high melting point is 2610 ℃, therefore molybdenum crucible is widely used for sapphire crystal growth furnace, quartz glass melting furnace, rare earth smelting furnaces and other industrial furnace, its working temperature environment in 2000 ℃.All the sizes can be manufactured based on customer's requirements
199911301. In a crucible for growing single crystals from the melt in a substantially inert atmosphere, the improvement wherein the crucible consists of sintered rhenium having a find as fabricated, density of 88 to 95% of theoretical density. 2. A crucible according to claim 1, wherein the sintered rhenium has a purity of at least 99.8%. 3.
Czochralski observed that the crystallized wire was in fact a single crystal, and the process was developed. Typically the crucible is made of tungsten or molybdenum. Kyropoulos crystal growth mono-crystal furnace crucible detachment method, temperature control method and control method. The spring cancels the torsional moment of the pulling gear.
KREMEN NOVO MESTO D.D., SLOVENIA - a wide range of products, reaching from raw flint stone to the fire resistant wet and dry silica / quartzite masses for cupolas furnaces, induction furnaces, transfer and treatment ladles, die casting pots and pans, quartz sand for foundries and metallurgy, quartz gravel for refractories and filter production
The sapphire crystal growing method used does tend to affect the crucible selection. During crystal growth via HEM, the temperature required for melting the alumina crackle is held constant. Because the thermal stress affecting the crucible is low, thin-wall spun molybdenum crucibles can be used.
It is an important part in high temperature furnace cause its high melting point. W crucible and other pure W & molybdenum parts can be used for sapphire crystal growth and rare-earth melting due to their and other excellent characteristics.

201983Kyropoulos process. The Kyropoulos method for quickly growing the large-size sapphire single crystal is greatly improved on the basis of the conventional Kyropoulos method, and has the advantages of shorter growth period, larger size and higher quality of the grown crystal, higher yield of the crystal, lower unit production cost and the like.
Sintering furnaces for molybdenum and rhenium sometimes employ this design, which can attain temperatures exceeding 2100 °C. Induction-heated tungsten crucibles are also used as susceptors to produce single crystal forms of sapphire (aluminum oxide). The tungsten crucible may hold the Al 2 O 3 directly, or it may contain a molybdenum crucible
The present invention addresses the problem of providing a crucible which is for use in growing a sapphire single crystal and which has a structure that can inhibit molten sapphire from being contaminated with a component of the crucible.
2019920Molybdenum, Tungsten, Tungsten Crucible, Tungsten Copper Electrode, Tungsten Tube, Heat Sink, Molybdenum Crucible, Tungsten Copper Contact Tip, Molybdenum Sheet, Tungsten Wire Company Introduction Zhuzhou Jiabang Refractory Metal Co., Ltd. is devoted to producing tungsten-molybdenum parts used in sapphire growth furnaces.
